DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an environmental testing device for conducting environmental resistance tests on control equipment and various other test products.

(Prior art, problems) There is a demand for environmental resistance testing of various specimens such as control equipment, and in the conventional environmental resistance tests, the surroundings of the specimen are exposed to various test environments. Therefore, the atmosphere of various measuring instruments attached to Mr. In addition, there are problems such as poor test accuracy and variations, and problems such as an increase in the number of tests and the need for retests due to failure or poor accuracy of the measuring instrument.

(Object of the Invention, Means for Solving Problems) The present invention has been developed in order to deal with the above-mentioned problems. A protective box containing a sample measuring instrument is provided, and it is comprised of a sensor disposed within the protective box, and a control gas blower and discharge adjustment valve that are connected to the protective box and controlled by the sensor. It is characterized by a configuration in which a measuring device environment control mechanism is provided in the protective box, and a protective box containing a measuring device of a test product is provided in an environmental test tank, and a sensor, a blower, and a sensor are provided in the protective box. By installing a measuring instrument environment control mechanism consisting of a discharge adjustment valve, it is possible to separately control the test environment of the specimen and the measuring instrument environment, significantly increasing the measurement accuracy and reliability as well as expanding the test range. Higher test performance,
It is an object of the present invention to provide an environmental testing device that has significantly improved efficiency and eliminates the above-mentioned problems.

(Example) An example of the present invention is shown in FIGS. 1 and 2,
In the figure, (1) is an environmental test tank whose periphery is defined by a low temperature tank (2), a high temperature tank (3), an upper wall (4), a lower wall (5), etc. ) is a low temperature chamber (2
) and a high-temperature tank (3) to adjust the desired temperature, and an appropriate mechanism (not shown) supplies and exhausts gas (air, etc.) and controls humidity, etc. The structure is such that the surroundings of the housed specimen (a) can be set up in a variety of test environments.

Further, in the environmental test tank (1), a replacement box Uυ containing a measuring instrument (kl) is arranged adjacent to the specimen (a), and the protection M (11) is equipped with a heat shield C131. A rubber sealing ring is provided, and the inside of the enclosure 01 is thermally insulated and sealed from the test environment atmosphere of the specimen (a) in the environmental test tank (1). The structure is such that an atmosphere is created.

Furthermore, a sensor α9 (for temperature detection, etc.) is arranged inside the protective box α1), and a blower pipe Qe and a discharge pipe (Iη) connected inside the protective box αυ are connected to the upper wall and the lower wall (
4) (51 is passed through × and extended outside the tank, a blower 0 seconds is connected to the outside of the tank in the blower piping GO, and a discharge adjustment valve (11 is installed in the outside of the tank in the discharge pipe aη, and the above-mentioned sensor(
19 signal cables (2I (2111) to the blower Q8
and said discharge regulating valve (connected to I9 to make them automatic 11i)
The configuration includes an instrument environment control mechanism with control functions.

In the figure, (6) is the measurement axis of the measuring instrument Ql, (18a) is the on/off switch of the blower section, Cυ is the rubber sealing gasket, is the filter, and (c) is the air blower. For example, a digital analog out measuring device is used as the device Ql.

(Function) The embodiment of the present invention has the above-mentioned configuration. In the environmental test tank (1), a test sample (Al) is placed by an appropriate mechanism (not shown), and air ( Alternatively, a suitable gas) is supplied after being adjusted to the desired atmospheric pressure and humidity, etc., and is also adjusted to a desired low temperature in the low temperature chamber (2) or to a desired high temperature in the high temperature chamber (3). The atmosphere around (a) is adjusted to the desired test environment.

Furthermore, a protective box (
Inside lυ, control gas (air) is supplied by the blower Qe through the blower piping (1119), while the control gas inside the protection box aυ is discharged from the discharge piping.
The exhaust amount is regulated by the exhaust control valve (II), and
The temperature inside the protective box Qυ is detected by sensor Q, and sensor Q! 19 detection code is sent to the blower Q19.19 through the signal cable 121CA. Since the drive is controlled by the input to the exhaust control valve (l■), only the environment of the needle measuring instrument (II) inside the protection box Qlllll can be freely controlled and adjusted.
The control gas supplied from 19 into the protective box (11) is filtered to remove dust and collides with the air receiver (c) to equalize the temperature, humidity, etc. inside the protective box aυ.

(Effects of the Invention) As described above, the present invention provides a protective box Ql containing a measuring instrument (11) for the sample (a) in an environmental test chamber that forms a test environment for the sample (a). In addition, there is a sensor inside the protective box α1), and a control gas blower and discharge adjustment valve connected to the protective box α9 and controlled by the sensor α9. Since the measuring instrument environment control mechanism is provided, the test environment in the environmental test chamber and the measuring instrument environment in the protective box can be adjusted independently, and the measuring instrument can be operated in a controlled, optimal environment. The measurement accuracy and reliability are significantly improved, and there are no restrictions on the use of measuring instruments.The test range (test environment conditions) of the specimen is expanded, and the measurement accuracy and reliability are improved. It has been significantly improved.

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various design modifications can be made without departing from the spirit of the present invention. .
